11 dpm_runtime_{suspend,resume)()
12When: July 2007
13Why: Broken design for runtime control over driver power states, confusing
14 driver-internal runtime power management with: mechanisms to support
15 system-wide sleep state transitions; event codes that distinguish
16 different phases of swsusp "sleep" transitions; and userspace policy
17 inputs. This framework was never widely used, and most attempts to
18 use it were broken. Drivers should instead be exposing domain-specific
19 interfaces either to kernel or to userspace.

317Why: The stacking of class devices makes these values misleading and
318 inconsistent.
319 Class devices should not carry any of these properties, and bus
320 devices have SUBSYTEM and DRIVER as a replacement.
